Can't register device on cloud [resolved]

Got my Omega2+ all set up with wifi and everything.
Trying to connect it to the cloud from the console, but when I click the "Register device on cloud"-button it gives me an iframe that points to https://registerdevice.onion.io/, a page describing what's great about the cloud but nothing more.

Device id and device key in the web request are correct and going to that link in browser actually makes the device appear online. (I changed the id and key in the code above so nobody plays with my device.)

Running device-client in verbose i notice that it tries to run ubus list -v which causes command failed. I think it should run ubus -v list for the json output. Anyway I tried with a wrapper script to switch the two parameters in only that case but that fails terribly (openwrt does not like it at all). Here is the output from device-client with a lot omitted as i have no idea what is sensitive:
